– 800 mm stretched mesh size allows passage of small specimens
– Sustainable fishing: 100 ~ 150 individual large tuna per year
– Passive fishing: non-target species released or sold; zero fish ‘trashed’
CCollections - research

CConclusionsBest concentration: 19,2 / 30,8 / 30,8 mg/L19,2 / 30,8 / 30,8 mg/L
– RECOMMENDED concentration: 20 / 20 / 5050 / / 5050 mg/L mg/L
CConclusionsAmquel :– Excellent results keeping ammonia low (< 0,50 ppm)
– 20 ppm in water seems to be sufficient for bioloads up to 18 kg / m3
Bicarb. / Carb.:– Excellent results keeping pH high (> 7,90 ppm)
– ...but 30 ppm in water is barely sufficient for bioloads up to 18 kg / m3
– 50 ppm is recommended
History:– Good record keeping allowed for better and better results
